Proguard no longer works with Retrofit

Question

I have found older questions which touch on the same subject but with the latest versions none of the available answers work for me.

I am using Retrofit in my projec

Answer 1

This configuration worked for retrofit with gson.

#Using for retrofit & gson
-keep class com.google.gson.** { *; }
-keep class com.google.inject.** { *; }
-keep class org.apache.http.** { *; }
-keep class org.apache.james.mime4j.* { *; }
-keep class javax.inject.** { *; }
-keep class retrofit.** { *; }
-keep class sun.misc.Unsafe { *; }
-keep class com.google.gson.stream.** { *; }
-keepclassmembernames interface * {
    @retrofit.http.* ;
}
-keep interface retrofit.** { *;}
-keep interface com.squareup.** { *; }
-dontwarn rx.**
-dontwarn retrofit.**

plus you need to add all the POJO classes which is used with retrofit just like below.

-keep class com.google.gson.examples.android.model.** { *; }
-keep class com.packagename.your.pojo.models.** { *; }

keepattributes like below

-keepattributes Exceptions
-keepattributes InnerClasses
-keepattributes Signature
-keepattributes Deprecated
-keepattributes SourceFile
-keepattributes LineNumberTable
-keepattributes *Annotation*
-keepattributes EnclosingMethod
